Benchmark CPU performance

Build CoreMark
For x86 platform:
[ ] # make compile XCFLAGS="-g -DMULTITHREAD=8 -DUSE_FORK=1 -DPERFORMANCE_RUN=1"

[ ] # make compile XCFLAGS="-g -DMULTITHREAD=4 -DUSE_FORK=1 -DPERFORMANCE_RUN=1"

[ ] # make compile XCFLAGS="-g -DPERFORMANCE_RUN=1"

For ARM platform:
[ ] # make compile CC=arm-linux-gcc XCFLAGS="-g -DPERFORMANCE_RUN=1"

Execute CoreMark
[ ]# ./coremark.exe  0x0 0x0 0x66 0 7 1 2000
